Show me a phone that cant have its battery replaced with tools, they are rare. My moto G4 has a replaceable battery, even if its not instantly removable. What exactly is your argument? In-the-field replaceable batteries arent coming back any time soon.
At the end of the day i plug my phone into a battery (one of a set of two specifically for my phone), not the wall. I keep a bank of USB batteries for my devices. That way i dont have to have a wire running next to my bed. The power comes to the phone/device, not the other way around, nor is the device left in some random corner. USB batteries are STUPID cheap now, think of them as wireless power accessories.
